- CHMP recommends marketing authorization for Cosentyx in polymyalgia rheumatica
- Drug becomes first IL-17A inhibitor approved in Europe for PMR if finalized
- REPLENISH trial showed doubled sustained remission rates versus placebo
- Treatment offers steroid-sparing benefits with consistent safety profile
- European Commission decision expected within two months of CHMP opinion

The European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has adopted a positive opinion recommending marketing authorization for Novartis Cosentyx (secukinumab) in polymyalgia rheumatica (PMR). The recommendation positions the drug as the first interleukin-17A (IL-17A) inhibitor licensed in Europe for this condition, targeting adults with inadequate response to steroids or relapse during steroid taper.
Clinical Trial Data
The opinion follows results from the pivotal REPLENISH Phase III trial, published in the New England Journal of Medicine and presented at the 2026 European Alliance of Associations for Rheumatology (EULAR) Congress. The global, randomized, double-blind study evaluated efficacy and safety across 27 countries.
Key findings from the trial include:
| Metric | Outcome |
|---|---|
| Primary Endpoint | Met for both 300mg and 150mg arms |
| Sustained Remission | Doubled vs placebo at week 52 |
| Safety Profile | Consistent with established profile; no new signals |
| Steroid Exposure | Reduced cumulative dose via steroid-sparing effect |
Patients were randomized into three arms: Cosentyx 300mg, Cosentyx 150mg, or placebo, all combined with a 24-week steroid taper regimen. Both active treatment arms met all primary and secondary endpoints, including complete sustained remission and time until additional treatment was needed through week 52.
What the Numbers Show
The data reveals a divergence between current standard-of-care limitations and the drug’s efficacy. While long-term steroid use—the existing standard—is associated with significant risks like osteoporosis and diabetes, Cosentyx delivered a steroid-sparing effect without introducing new safety signals. This suggests a potential shift in risk-benefit profiles for PMR patients, who currently face up to 40% relapse rates in the first year under conventional therapy.
Regulatory Pathway
Following the CHMP recommendation, the European Commission is expected to issue a final decision within approximately two months. If approved, Cosentyx will expand its portfolio beyond current indications in psoriatic arthritis, plaque psoriasis, ankylosing spondylosis, non-radiographic axial spondyloarthritis, and hidradenitis suppurativa.
Patrick Horber, M.D., President of International at Novartis, stated that the approval would represent an important step in transforming care for those living with PMR, building on the drug’s established impact in autoimmune disease.
